C) A coil of 115 turns is wound onto a ring former as shown in Figure Q2c (overleaf). The ring is of average radius 0.15 m, cross-sectional area 2 x 10-4 m² and relative magnetic permeability 2500. i) Determine the reluctance of the magnetic circuit. 5 A secondary winding of 250 turns is added and a load of 300 2 is connected to the secondary coil. A sinusoidal ac voltage of 15 V (root mean square) is applied to the primary winding. Assume that the transformer is ideal. ii) Determine the impedance of the secondary referred to the primary. 4
